It will be interesting when space craft are as reliable as autonomous cars?
India and Israel crashing onto the Moon.
Will the next generation of space vehicles have Tesla autopilot systems on board?

Some of this stuff makes The Expanse Technology look dated.
Stainless steel rockets :o
Which Pi generation will be able to do what Tesla CPU's can do now?

Probably not 1.2?
Still trying to get Yolov3 to work ;)

Space is difficult. Very VERY difficult. More craft have crashed on extraterrestrial bodies than landed safely.
Why would a spacecraft require a car auto drive system? No traffic lights in space.
None of this stuff make Expanse look dated. Expanse is about 200 years away!
Stainless steel rockets have been around since the beginning of the space programme. Atlas was a SS balloon tank.

Reminds me of a recent (as in within the last week) article about a Tesla "crash and burn". The parents are suing Tesla because their 19 year of son and one passenger died (the other passenger was ejected in the crash and survived). They'd best hope no one of my opinions is on the jury. The speed limit was 30 mph, with a 25 mph (marked) curve. The Tesla was going 116 mph. PEBSAS.

Indeed. Humans could never control a SpaceX Starship through its reentry phase.

A proper override in this case would allow navigational changes based on human decision making without the need to take manual control of every positioning and stabilizing device.

ejolson,

I know nothing of navigating in space or avoiding space pirates.

My understanding of the Apollo missions was that it was impossible for a human to make the calculations required to get into moon orbit and such. Hence the famous AGC.

Spacecraft will never be as reliable as cars.
Depends on who's cars or spacecraft.
Everyday Astronaut has some figures on engine reliability.
Could car radar be used for autonomous landings?
Parallel parking algorithms be used for docking?
Run that code on Pi's?
Tesla C/GPU's run at about 250TOPS, which is a heck of a lot more than the Pi4.
How much more and is the Tesla code getting better without changes to the hardware?
None of this stuff make Expanse look dated. Expanse is about 200 years away!
How far has the Pi come in 8 years? Add 200 years to that?
How far has the current new gen rockets come, add 200years?

Atlas hulls needed to be kept pressurised as the SS was very thing, I think SpaceX don't need to do that.
2019-1957 = 62years, ok maybe rocket development has not been very fast.

Perhaps Pi's on Moon mining rovers, with level 5 autonomous AI?
Without roads and traffic lights would level 5 be needed?
Terrestrial mining trucks are basically that now?
Do they need 250TOPS on the moon?

A reasonable conjecture would be that there is an inventory surplus of 1GB and 2GB models, but due to unexpected demand the revised 4GB model is already in production and shipping.

That's one way to look at it.

On the other hand, the bare PCBs that arrive at the factory to be populated with parts should be identical for all three versions. The parts put on the boards should also be identical, except for the DRAM package. That makes it odd that there wouldn't be v1.2 for the 2GB and 1GB, as well, whether or not existing inventory has been cleared.

It would be interesting to see the sales numbers for 1GB, 2GB, and 4GB PI4s.
In the UK, both Pimoroni and The Pi Hut seem to have depleted their 1GB stock, looks like the 1GB version will.get the V1.2 treatment soon.
For me, USB-C power delivery bug is an issue, as I travel a lot with my Pi4, I want to just take USB-C chargers and charging cables that conform to the PD standard, I don’t want to carry one special cable just for the Pi, because, in a hurry, i will probably grab the wrong one.

This is the first time since the issue was reported that someone has come up with a decent reason why they want the issue fixed!

It's not a special cable you need, it's the exact opposite. It's a completely normal USB-C cable. The ones you already have are the special ones.

You've got to realize this is a bit of a disingenuous response, right? It's not that that user is referencing a special cable (e.g. cable features) but a special cable in that it's different than a cable already owned.

When I want to bring a USB-C cable somewhere I want it to work with every device because that's one of the best possible parts of USB-C behavior. I can have a 10gbps data cable that can also charge 100W devices and also swap to charge just my iPad or phone. While it's a bit of a stretch that Pis regularly move around, it's not a stretch to want to have some fungibility of use on cables and some people do bring Pis on the go because they are that portable.

Not sure if already been posted since I replied to that thread almost 2 months ago but I go no email notifications so I thought it was dead or nobody answered, I can also say that my pi works with an 87w USB PD charger over a 3A cable, don't have an E-MARK one (the 5A ones) to try it with tho, will later (it's wall mounted and with a fan so it takes a while to shut down properly and get to the bare board) post pictures of the board and try it with a 65w "wotobe" one, the lenovo that came with my laptop and my 65w powerbank.

Ok, here are the photoshttps://imgur.com/gallery/mkwGRM6, also tried the 65w chargers (wotobe and lenovo), the powerbank and the type c/tb3 port of my laptop (yoga 730 IWL) with 2 different 3A cables and a 10gb/s cable that came with my orice external nvme enclosure and it worked with all 3 cables in all scenarios (only thing that didn't work was the pd led on my powerbank but it still turned on and worked just fine so it doesn't matter and doesn't turn on even with my phone unless the screen is off) so out of the like 10 combinations everything worked just fine on the v1.2 c03112
